Structural analysis of the patented new product transmission system of steel pipe cutting machine Wang Boping Li Dengzhao Ma Chaohua; 1. Taiyuan Heavy Machinery College, Taiyuan, Shanxi 030024; 2. Taiyuan Federation of Trade Unions, Taiyuan, Shanxi, 33. Taiyuan Heavy Shanxi mechanical cutting, its structure is new and convenient The steel pipe has a flat incision and high working efficiency. It can be used for the mechanical manufacture of various steel pipes with different diameters and wall thicknesses, in the process of construction and construction installation, steel pipe wheel extrusion grinding wheel cutting and gas welding cutting. These steel pipe cutting methods are different, and there are disadvantages such as high cutting efficiency and strong labor. Moreover, the method also has defects such as tapered cuts such as roller squeeze cuts rough and uneven, such as gas welding cutting noise, such as grinding wheel cutting is not easy to work on site. In response to the above questions, in recent years we have organized scientific research and research, designed and developed a novel structure, high efficiency and easy operation, which can cut steel pipes of different bamboo diameters, thicknesses and materials with one-force cutting. This machine has won a national patent. Patent No. 93201081.41 Transmission system structure characteristics and analysis The machine adopts the original design of planetary motion, 1 force cutting motion is unique in generation, its movement is simple 1 tool blade cutter has the main cutting motion in the process of work, rotation, circumferential feed motion and radial The feed movement is in work, the workpiece steel pipe is fixed, the cutter can achieve the circumferential cutting feed around the steel pipe and the radial 1 cutter feed while rotating the main movement of the blade cutter through the above movements. The machine's Bian Dao 1 moves. The characteristics of the transmission system of Zhou Jiao's feed memory and radial feed motion are compared with the overall structure of the machine. The structure of the main cutting motion system refers to Structure 2. The steel pipe cutting machine is composed of a frame 29, a left bottom plate 26, and a right bottom plate 42. The left side plate 2 right side plate 67, 1 cover plate 2, left support 14, right support 69 The center hole of the left and right brackets is concentric with bolts and the frame is tightly connected, and the hole diameter is 200. This model can cut the outer diameter tube. The machine is equipped with a set of diameter sleeves 12 with different inner hole diameters. Each diameter of the rotation support is 13 threaded connections. Before the operation of the machine, you can choose the appropriate inner diameter hole diameter of the complex steel pipe 59 After the cut part is aligned with the blade cutter 79, the left end of the steel pipe is fastened by a set screw 8 connected to the left bracket 14 evenly distributed in the circumferential direction.
Make it + turn or move the start switch to start the motor 46, through the angle belt 54 pulley 53 too pulley shaft 51 pinion 52, the coupling gear 57 gear 71 drives the lever base 72 to rotate, the lever base is connected to two ball heads Draft date 19982, Dengzhao 1962, male, Yongji, Shanxi, engineer, undergraduate; Ma Zhaohua, 1960, male, Shanxi Taiyuan, engineer, 198 Yi graduated from Taiyuan University of Technology, undergraduate.
The rod 73 and the split ball half tile 74 are connected by a bolt 75 as a body and contain the ball head of the club head, and the ball half can be rotated universally with respect to the ball head. . The sliding sleeve 77 is provided with a sliding rod 78 which is connected to the ball half-ball head rod by an end-like method. The motion and power transmitted from the motor through the above transmission system structure are transmitted to the blade cutter 79 mounted on the floating shaft 85 and clamped by the two-piece clamping plate 81 to rotate the blade cutter to constitute the main cutting steel pipe.

The flood spring 40 set on the large pulley shaft is to ensure the tight coupling of the clutch through the small bevel gear shaft 34 small bevel gear 30 large gear 22 worm shaft 23 worm gear 3 coupling frame 2, rotary support 3 shift fork 6 dial 4 Toggle lever 7 Toggle lever thymium 86 guide fork 1 to drive the circumferential rotating main cutting movement of the floating bearing seat 83, and along the revolution of the steel pipe to be revolved in the circumferential feed motion, a coupling frame 20 connects the worm gear and the rotating support sleeve 13 with bolts At the beginning, the rotating support sleeve and the guide fork are connected with a shaft bolt. When the circumferential feed movement is performed, the ball head rod 73 ball half tile 74 sliding sleeve 77 sliding rod 78 dial lever seat 72 gear 71 and sleeve double gear 57 The upper rotating bearing seat 66 starts to move in the circumferential direction with the blade cutter 79. The ball half tile rotates relative to the direction of the ball head and the sliding sleeve 77 slides axially relative to the sliding rod 78 to ensure that the wide blade cutter is fed in the circumferential direction. Radial feed and cutting position of the steel pipe. Thus, by bearing 84 pottery and 85, driving the blade cutter to drag the payment page on the rotating shu, which is the key to the correct movement position relationship between the main movement and the feed movement. The pressure spring 76 It guarantees that the sliding sleeve and the sliding rod are fed during feeding. The 1.3-inch feed motion system structure. The steel tube cutting machine performs radial feed motion by rotating the feed wheel 17 to make the flat plate 5 threaded with the feed wheel to the right. Movement, because the feed wheel is axially blocked by the backing ring 15 and the worm wheel 3, the threaded outer diameter of the feed wheel and the threaded inner diameter of the disk mesh, the feed wheel rotates relative to the flat disk, which can promote the displacement of the flat disk. Rotating the feed wheel can move the flat plate and the shift fork 6 fixedly connected to it to the right, so that the shift lever 7 moves to the right through the grooved worm wheel, and the right end of the shift lever drives the shift lever pin 86 along the guide fork 1 The guide groove moves in the direction to make the floating bearing seat 83 cutter along the steel pipe to make the feed movement, so that the slice cutting can be realized in the main cutting movement of the rotation and the circumferential feed movement of the revolution, and can also be carried out along the steel sign being cut. After the steel pipe is cut, the feed wheel 17 is reversed to move the blade cutter up, and then the dial is moved to the right to disengage the clutch. The circumferential feed movement can also be stopped. The unloading material enters the fixed length for the next working cycle of cutting steel pipes.
2 Conclusion The machine adopts a unique and novel tool planetary motion method to solve the problem of motion coordination between the circumferential feed movement and the radial feed movement of the small cutting movement of the steel pipe during efficient cutting of the steel pipe, and overcomes the defects in the traditional steel pipe cutting method The cutting efficiency is high, the cut is smooth, the operation is simple, and the labor intensity of the operator is reduced. This patented new product can cut low carbon gauge medium carbon high carbon maple alloy steel pipes and various water gas steel pipes, welded steel pipes, seamless steel pipes for hot and cold vehicles, cast iron pipes and non-ferrous metal pipes.
